It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
It should be noted that the description relating to "first", "second", etc. in the present invention is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The washing machine comprises a machine body and a detergent box assembly arranged on the machine body, as shown in fig. 1-18, the detergent box assembly comprises a detergent box 1, a detergent drawer 2 and a liquid storage box 5 which are movably arranged in the detergent box 1, a driving device, a liquid level detection unit and a liquid pump 15.
The detergent box 1 comprises a water inlet box 8, a water distribution plate 9 and a water distribution plate cover 10, wherein the water distribution plate 9 is installed on the water inlet box 8, and the water inlet box 8 and the water distribution plate cover 10 are respectively positioned on two opposite sides of the water distribution plate 9. The water diversion plate 9 and the water inlet box 8 jointly define a containing space 11 which is open at one end and is used for containing the liquid storage box 5 and the detergent drawer 2. The water diversion plate 9 and the water diversion plate cover 10 jointly define a water inlet cavity 13, the water inlet cavity 13 is communicated with the accommodating space 11, and the water inlet cavity 13 is connected with a water inlet pump 14 to convey water to the water inlet cavity 13. The water diversion plate 9 is provided with a diversion channel communicated with the accommodating space 11 so as to guide the entering water flow into the accommodating space 11 and discharge the water flow into the washing machine through the detergent box 1.
